Embodiment
The present invention is further described below in conjunction with the accompanying drawings；
In the accompanying drawings：
First embodiment：
A kind of forged hardening method of shackle peculiar to vessel, it is characterized in that：Shackle 1 after forging is put on streamline, detection temperature
Afterwards, shackle 1 is put into quenching unit 2, secondary heat treatment, the sampling observation of final finished physical property is carried out after one-time detection；It is described
One-time detection be case hardness detection, in the specified location of shackle 1 then sanding surface is beaten with portable hardometer with emery wheel
Multiple points are averaged, and lining bar also needs to carry out hardness test；It is not only easy to operate, improve quenched martensite ratio, Er Qie great
Energy consumption is reduced greatly, improves operating efficiency, reduces the significant effect of cost, improves the cost performance for unloading buckle product.
Also need to forge simultaneously and the material of shackle 1, forging ratio, cross sectional shape, final diameter and forged harding parameter phase
Same lining bar；Lining bar carries out the operation such as being heat-treated simultaneously with shackle 1, is not only easy to be contrasted during detection, and can use
Lining bar does the detection that some shackles 1 can not directly be done, such as mechanical test.
Described detection temperature, temperature are 850 DEG C -950 DEG C；If the hardening heat of shackle 1 exceeds the scope of process stipulation,
Temperature and the quenching of process stipulation should be then reheated to, because the nominal size of shackle 1 is from 14mm to 152mm, small dimension
The Forging Equipment Speed of shackle 1 is fast, and it is of a relatively high to enter coolant-temperature gage；Big specification 1 Forging Equipment Speed of shackle is slow, and it is relatively low to enter coolant-temperature gage, therefore
Technological parameter needs to be adjusted in good time according to different products.
Cool time of the described shackle 1 in quenching unit 2 must not be less than 10 minutes, ensure that the effect of quenching.
Described quenching unit 2 includes pond body 2-1, the water conservancy diversion for being easy to cooling medium 2-2 to circulate being connected on pond body 2-1
Device, and the grid structure 2-3 being arranged in pond body 2-1 bottom interior wall；Described grid structure 2-3 and pond body 2-1's
Space 2-4 is left between bottom interior wall；Described cooling medium 2-2 is water；Described grid structure 2-3 causes shackle 1 and pond
Body 2-1 isolates, and the space 2-4 of formation is not only advantageous to shackle 1 from multiple angles, comprehensive quenching, improves the effect of quenching
Fruit, and be advantageous to the discharge of foreign matter；Described guiding device includes cooling medium 2-2 several imports 2-5, cooling medium
2-2 several outlets 2-6, and the water circulating pump component 2-7 of pond body 2-1 bottoms is arranged on, it ensure that pond body 2-1 cooling
Medium 2-2 amount, ensure that cooling effect；Shape between described grid structure 2-3 cross section and pond body 2-1 bottom interior wall
Structure in echelon, several groove 2-8 for being easy to foreign matter to pass through are provided with surface, be advantageous to the foreign matters such as oxide skin precipitation；Institute
The outlet 2-6 stated is positioned close to trapezium structure side-walls, is communicated with groove 2-8, is easy to foreign matter to discharge.
Described secondary heat treatment is tempering, and temperature is 590 DEG C -620 DEG C, compared with traditional 580 DEG C -600 DEG C,
Austenite is more stable, and the ratio of martensite for quenching to obtain is higher, and quenching effect is more preferable, and shackle 1 exist a large amount of dislocations and
Substructure, further increase tempering resistance.
Above-described embodiment is only intended to clearly illustrate the description that the present invention is made, and is not the restriction to embodiment,
To those of ordinary skill in the art, other various forms of changes or change can also be made on the basis of the above description
Dynamic, there is no necessity and possibility to exhaust all the enbodiments, and the obvious change or change thus amplified out
Among moving still in protection scope of the present invention.
